Ceiling hinge assembly

ABSTRACT

An improved hinge assembly disclosed in this invention makes the installation more convenient by redesigning the single-axle hinge structure, which comprises a base and a rotary rod, and the connection between the rotary rod and the base is improved by replacing the protruded axle at one end of the original rotary rod with a connecting groove, and makes the pivotal connection of the rotary rod easier and the connection more secure.

FIELD OF THE INVENTION

The present invention relates to an improved ceiling hinge assembly,more particular to an improved single-axle ceiling hinge assembly thatmakes the installation easier.

BACKGROUND OF THE INVENTION

If a glass door is built, most constructions usually adopt floor hingesas building materials in order to save time and effort for theconstruction. However, a dark chamber must to be installed at the floorof the construction before such construction is taken place. When thefloor hinge is in use, the floor hinge has to keep a gap between thedoor and the floor. Therefore, an airtight strap is usually used toimprove the situation of such gap. If we have to clean the floor, theairtight gap cannot stop the dirty water from flowing. If such hinge isused for a glass door, it is necessary to install a set of metallicbracket onto both upper and lower edges of the glass door beforeinstalling the hinge to facilitate fixing the glass door in a fixedposition.

The feature of a frameless glass door resides on its good heat and soundinsulation, but its pivotal connection is done by installing the floorhinge between the glass door and the frame. Therefore, there is a gapbetween the door and the floor, which will reduce the heat and soundinsulation effect. The U.S. Pat. No. 5,077,864 disclosed a hingeinstalled on the side of a door, and the design of such hinge is dividedinto two sections; one section is fixed onto the door frame, and theother section is connected to the door panel, and the two sections ofthe hinge are pivotally coupled. The hinge is lubricated when needed toavoid rusting, and the rust makes the door uneasy to open. Furthermore,the installation of the hinge requires precision that may be affected byhuman factors. Therefore, it is necessary to adjust the hinge and thedoor, which may cause the correction and adjustment problems.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to improveconventional ceiling hinges that are uneasy to install and poor at itssealing function, and improve the ceiling hinge structure to provide amore convenient way of installing the hinge. The present inventionrelates to a single-axle design, comprising a base and a rotary rodcoupled to the base, and the head of the rotary rod is designed as aconnecting groove, which is coupled to the connecting axle of the base.Adjustment along the vertical direction can be made by rotating a screwon the rotary rod. The body of the rotary rod has a plurality of holesfor connecting the door panel by fixtures.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 1 for the installation of the hinge to a door panel(such as a glass door 4) according to a preferred embodiment of thisinvention. The ceiling hinge installed at the top of the glass door 4comprises a base 1 and a rod head 20 of a rotary rod 2, such that whenthe glass door 4 is rotated, the

the rotary rod 2 of the hinge according to a preferred embodiment ofthis invention. The rod head 20 of the rotary rod 2 has a connectinggroove 201, and such connecting groove 201 is a square groove, and along groove of the same size is disposed around each of the four sidesof the grooves. A plurality of screw holes 202 disposed on the sides ofthe rod head 20 for fixing and adjusting the connecting axle 10 of thebase 1 and the connecting groove 201 by screwing a screw 203 to fix theconnecting axle 10. The connecting axle 10 is a cylinder having a flangecoupled to each of the four sides of the cylinder, and the groove of theconnecting groove 201 is larger than the cylinder of the connecting axle10. The rod head 20 of the rotary rod 2 can be adjusted by tighteningthe screw 203 in order to make a vertical adjustment to the rotary rod 2that will make the installation of the door panel much easier. Aplurality of the holes 211 is disposed on the rod body 21, and thefixture 3 in this preferred embodiment adopts a screw rod 31 as thefixture 3. Further, a primary cushion 311 and a secondary cushion 312are added to the contact section of the screw rod 31 and the glass door4 to prevent the collision of the screw rod 31 and the glass door 4.Since glass is a fragile material, and if the glass material hasdefects, a slight collision will turn the defect into a big one. Toavoid the occurrence of such situation and the collision between therotary rod 2 and the glass door 4, the contact surface 204 between therod head 20 of the rotary rod 2 and the glass door 4 is designed, inaddition to the primary cushion 311 and secondary cushion 312.

Please refer to FIG. 3, the improved hinge assembly in accordance withthis invention can prevent itself from being loosened, and itsinstallation is easy and can be used to adjust the door panel (such as aglass door 4). In the top of the door panel (Such as a glass door 4),there is the base 1 be settled. The rotary rod 2 is connected to thebase and the door. In the bottom of the door panel corresponding to therotary rod 2, there is a supporting rod 5. It can also save a plasticcup or metallic bracket for installing onto a glass door 4 or window bydirectly connecting the rotary rod 2 and the glass door 4.
